m/z distribution histogram
Description
This module creates m/z distribution histograms of all m/z values in mass lists across specified scans.
The binning width, in which the m/z values are counted, can be changed dynamically.
The number of scans that contain a specific m/z value (bin) are plotted.

Method parameters
- Raw data file, scans filter and mass list
- Specify the scans and mass lists
- m/z range
- Limit the range of the histogram to save performance
- Retention time range (optional)
- Limit the scans to a specific retention time range
- m/z bin width
- The binning width to count m/z value occurance in scans (can be changed dynamically in the dialog)
The dialog
The "bin width" and "shift bins by" parameter automatically listens for changes and updates the chart (indicated by red/green label above).
Apply a Gaussian fit to a distribution.
Key bindings
Use the arrow keys (left/right) or buttons to jump to the previous or next distribution.
Mouse gestures
As in most of the other charts, mouse gestures are available to facilitate the chart control.
- Use modifier keys (SHIFT/CTRL) and drag the mouse over the axes to zoom, translate and auto zoom the opposite axis
- Double click on the plot to jump back in the zoom history (CTRL+double click to jump forward)
- Double click on a axis to auto zoom
